Overview
Rn52-breakout is an open-source printed circuit board by festlv, from the festlv/rn52-breakout repository on GitHub, published under the MIT licence. It is a 2-layer board of 58.9 × 29.5 mm with 18 parts on 18 nets, routed with 104 tracks and 0 vias.
It is built around the LM317T. Its parts include 6 connectors, 4 resistors, 3 diodes, 2 ICs and 1 capacitor. It belongs with the interfaces and adapters and radio and wireless boards of this library.
Main components

README.mdRN52 breakout board
KiCad schematics, library symbol and footprints for RN52 Bluetooth module.
The following functionality is broken out:
- UART's RX/TX pins
- GPIO9 (command/data mode selection)
- GPIO7 (UART baud rate selection)
- GPIO4 (factory reset switch)
- PWREN (enable power)
- LED0, LED1
- Audio output, in a really, really dumb way. You should use amplifier with differential input.
Be warned- the PCB was designed for parts I had on hand and home-made production process (single layer, fat tracks).
I had wrong footprint for linear regulator at the first try- it's now been fixed in master.

Questions
How big is the Rn52-breakout PCB?
It measures 58.9 × 29.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Rn52-breakout use?
18 parts, built around the LM317T. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Rn52-breakout KiCad files?
From the festlv/rn52-breakout repository on GitHub, at the commit this page was made from: the board is rn52-breakout.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rn52-breakout design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
